I dont know if it is helpful, but I recovered the use of an old BIOS
password protected Digital laptop once by shorting the serial data out
line on the NVram chip to ground using a long wire that I routed outside
the case, powering up the laptop, which then complained that the NVram
was corrupt (gosh!) - I then entered the bios setup utility, typed in a
new password, cut the wire, and pressed 'enter' to set the password
(write it to memory) - Worked like a beaut.

there may be a way to "short" the cmos to clear it,
sorry I can't help with IBM specifics, the link provided previously in regards to the
Atmel chip looks like your best bet,
but also looks like you'll need to take apart more than you'd prefer.

Dan,
You seem to be missing the point of my request for help.
1. The laptop is worth about $50.00, I'm not spending $1200 to recover data off the
HDD, and neither is my friend who it belongs to. She is upset losing the $100 it cost her
two years ago.
2. The laptop doesn't boot. It asks for a password. This is in the BIOS. It can't
be bypassed to boot from floppy or CD. Without this password, the system is bricked. There
is no way to recover it other than changing the logic board and HDD. Since all I want is
the HDD data, that is not the solution.
There is a way to recover the password, but nobody will tell me where the TPM chip is
located on the 600e logic board. I don't want to just take the laptop totally apart. I
want to take as little apart as possible.
I'm hoping someone knows the IBM master password so I can get into the bios and reset
the system. Barring that, this system is junk.
Thanks anyway.

take it to a data recovery place, ask for a free estimate.
be prepared to pay $1200 or more.
as for the CMOS, you can still wipe it.
remove the HDD, then boot either floppy or CD that would bypass that password,
would also confirm exactly how it is locked.
you can still try to contact IBM for recovery (for a large fee I suspect)
otherwise you're SOL
Dan.
